Free NES (6502) assembler and linker

Purpose

This program reads symbolic 6502/RP2A03/RP2A07 machine code and compiles (assembles) it into a relocatable object file or into an IPS patch.

The produced object file is binary-compatible with those made with XA65.

History

This program was born when Bisqwit needed to have something for NES that is already accomplished for SNES by snescom.

Linker

This package also contains a linker.

The linker can also be used to convert IPS patches into binary files (an empty space is assumed to be the original file), with the following command:

neslink input.ips -o result.bin -f raw
